Specification of Letters Patent.

Application filed September 26,1905. Serial No. 280,163.

T0 /L/Z 7171110771, if T11/ty cm1/cern:

Be it known that l, EUGENE S. (uULL, a. citizen of the United States, and a resident of Sedalia, in the county of lettis and State of Missouri, ha ve invented a new and useful lmprovemcnt in Sheathing-Laths, of which the following is a full, clear, and exact descriptlon.

The purpose of the invention is to provide a combination ot sheathing and laths for plaster and stucco work on walls or ceilings, so constructed as to oil'er the least possible obstruction to the plaster-keys and a maximum of bearing or locking surface, and, furthermore,v to so construct the article tllat each lath is'capable of being almost completely surrounded by plastic material.

Another purpose of tle invention is to provide a construction of sheathing and laths wherein the two factors are integral parts and which ma)v be economically and readily produced and wherein the laths will be equaiiy spaced from each other and from the sheathing, enabling much more smooth and regular work to be accomplished than ordinaril)l and with the expenditure of much less material.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to behad to the accompanying drawi1'1gs,.forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspec "Je view of a corner portion of an apartment, showing sundry of the combined sheathing and lath laid to form the side walls and ceiling. Fig. 2 is an inner face view of a piece of sheathing and combined lath. Fig. 3 is a transverse section taken substantially on the line 3 3 of Fig; 2, and Fig. 4 is a longitudinal section taken practically on the line 4 4 of Fig. 3.

In the construction of the article the lathsl and the sheathing are made from one piece of material of suitable size, and A represents the sheathing, and B the laths, which are at the inner face of t-he sheathing, extending in parallel lines at an equal distance apart from end to end of the )iece of material from which the article is ma( c.

The upper edge 1t) of the combined sheathing and laths is inclined from the back of the sheathing upwardly, as is shown in Fig. 3, and a corresponding inclination 11 is given t0 the lower longitudinal edge of the said article, as is also shown in Fig. 3. ln producing the laths B saw-kerls 122 are carried from end to end of the material at its inner face, the said kerfs being at equal distances apart and of uniform width, and in producing the said kerfs the uppermost one is so placed as to have a lath B at the upper edge of the material and to have a kerl 13 at the lower edge of the material, so that when two of the articles are made to abut the upper lath B of the lower article will be spaced an equal distance from the lower lath of the upper article, as is the spacing between the intermediate laths, so as to provide a perfectly uniform keyingsurl'ace when the combined laths and sheathing are placed in position on a building.

The laths B are separated from the sheathing A throughout the entire length of the piece by means of a winding or circuitous rib C, forming an integral portion of the laths and sheathings at regular intervals, and in producing this rib vertical or trans- Vverse saw-kerfs are introduced of given lengths, of which 16 is a complete kerf and 14 and 15 portions of corresponding kerfs at opposite edges of the piece. The saw is introduced at one edge to produce the kerf 16 and at the opposite edge to produce the duplicate kerfs, so that, preferably, the said rib or bearing C assumes a circuitous format-ion, (shown in Fig. 4,) comprising longitudinal members 17, 17, and 19, adjacent to the edge of the material, and diagonal members 18 and 1S, which incline in the o posite direction; but it will be understood tliat the lath may be of any desired length and that the rib U will appear as a series of diagonal members connected by longitudinal members arallel with opposite side edges of the artic e. The kerfs may be produced in any convenient manner.

It will be observed that by means of this construction the laths are integral with the sheathing, yet are separate therefrom for the major portion of their lengths, and that the laths are a uniform distance from the sheathing as well as a uniform distance from each other.' It will be further observed that the connected and yet largely independent individuality of each lath B is provided for by the blind and hidden bearing or connecting ribs C, which are more frequent yet have less liability to obstruct plaster-keys than when ordinary lat-hs are em loyed, wherein the parts corresponding to t e said bearings IOO IIO

are the uprights to which the laths are attached. Each lath is capable of heilig practically surrounded on all sides by plastic niaterial, and the laths being produced upon the sheathing A in tlie'inanner shown and described are mechanically and accurately divided one from the other and from the sheathing or backing. all spacing being uniform and consistent with the best requirements.

The uniforir 1d regular spacing between the laths and the sheathing ell'ect a considerable saving in material, since the plaster in ordinary work is often forced between and back of the laths to such an extent as to fall down and be of no service. Again, when the improved device is employed great solidity is given to the wall by reason of the strong, close, and compact combination of the two thicknesses of wood alternating with the plaster, presenting an even plastic surface when the wall is completed, together with a strong combination of heat and cold resistance.

The winding or circuitous position of the bearings or ribs C binding the laths and sheatliings constitutes a continuousr rail- Support when the article is laid at every part in the length of each article, and therefore the article is adaptable to any studding or joists however spaced. The beveled edges 10 and l] when abutting sections are. brought together constitute a. more effective lock than nails or tongues or grooves, although the latter may be used if found desirable. Y

I desire it to be understood that any desired number of laths may be formed integral with a piece of sheathing and that the longi-` tudinal keifs 12 may be made intermittent instead of continuous, as shown, without departing from the spirit of the invention.

In Fig. 1 I have illustrated the application of the improved lathing article to a structure in which D represents the ceiling lathing and sheathing, E the siding lathing and sheathing, and'F the supports to which the sheathing is secure-l.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. As an improved article 0f manufacture, a sheathing and laths integral with the sheathing, separated therefrom a predetermined distance in their length, and separated' from each other.

2. As an improved article of manufacture, a sheathing and laths formed integral with a sheathing at intervals in their length and separated from each other, one of the laths extending to a longitudinal edge of the sheathing, another latli being spaced from the opposing longitudinal edge, both edges of the sheathing and the laths where they inclined from the back of the sheathing.

3. As an improved article of manufacture, a sheathing, laths formed integral with the sheathing, separated from the sheathing at intervals in their length and separated from the distance'betwecn the laths. l

4. As an improved article of manufacture, a sheathing, a circultous rib or bearing intehaving longitudinal members connected by being adjacent to the edges of the sheathing, and laths secured to the rib and spaced from each other. In testimony whereof I have signed my name to this specification in the presence "of two subscribing witnesses.
